The Sony PlayStation 4 (CUH-1200 series) relies on the power supply unit (PSU). This component converts high-voltage alternating current (AC) from your wall outlet into stable direct current (DC) required by the console's motherboard.
A Metal Oxide Varistor (MOV) is tied across the lines. If a lighting strike or grid surge hits, it drops resistance immediately to short-circuit the line and break the fuse, saving downstream ICs.
⚠️ The ADP-200ER operates at lethal voltages. The large capacitors on the primary side can hold a dangerous charge long after the unit is unplugged. Do not proceed unless you have experience working with switch-mode power supplies.
Powers the APU (Accelerated Processing Unit), GDDR5 memory, cooling fan, and hard drive. Rated at approximately 16A.
A fuse rarely blows on its own. It is usually a symptom of a dead short circuit further down the line.
: The unit is rated to provide 12V DC at approximately 16 Amperes .
The ADP-200ER uses a :
Do you have any available? (e.g., multimeter, soldering iron, oscilloscope)
Use a multimeter in continuity mode to check the 12V output prongs. If they show a dead short to ground, replace the shorted secondary MOSFETs. Safety Warnings for Repair Technicians
~200W sustained output capacity Circuit Blocks Architecture
: It utilizes dual MOSFETs to drive a power transformer.

: A standard sacrificial fuse acts as the gatekeeper. A short circuit anywhere down the line reliably forces this fuse open.
: Composed of Class X capacitors, Class Y capacitors, and common-mode chokes to scrub high-frequency noise from the power grid.
